SPECIFICATION forming part of Letters Patent No. 653,151, dated July 3, 1900. Application filed December 23, 1897. Serial No. 663,150. (No model.)

To all whom it may concern:

Be it known that I, FRANK I-I. PIERPONT, a citizen of the United States of America, residing in Berlin, Empire of Germany, have invented certain new and useful Improvements in Line-Casting Machines, of which the following is a full, clear, and exact description.

The present invention relates to line-casting machines; and it consists of a slide located at the mold-inlet and adapted to be pushed up or down after the mold has been filled with molten metal and to cut 0d the bur at a point below the proper type height.

In order to render the present specification more easily intelligible,reference is had to the accompanying drawings,in which similar letters of reference denote similar parts throughout the several views.

Figure 1 is a horizontal section through the mold, slide, and a part of the pot-nozzle; Fig. 2, a section and elevation of one form of slide; Fig. 3, a vertical section through a modified form of slide, and Fig. 4. a perspective View showing one form of device for operating the melting-pot and slide.

Referring first to Fig. 4, the melting-pot is mounted in the well-known manner'on a slide 3, which may be reciprocated by any suitable means from a lug s or the like. The nozzle a of the pot closes onto the slide hot the mold when the pot is advanced, and as the pot recedes after the casting has been madei. e., the mold filled by the action of the plunger of the pot--the mold-supporting plate a is tipped on its pivot e by the action of the connecting-bar 1 which is pivoted to the said plate a and connected by a pin-and-slot connection 11 to the pot-supporting standard. The slide 1) is suitably guided on the plate 2 by means of its stem 25', which is provided with a laterally-extending pin i, adapted, to move in a stationary cam groove t and when the moldsupporting plate is tipped the said groove is so shaped as to move the slide 7) on the face of the mold, as hereinafter more particularly set forth.

The present invention consists, essentially, in the particular formation of the slide, which is adapted to break off the bur of the line cast in a plane below that of the proper type height.

As will be seen from Fig. 1, the mold m is closed at the back by the row of letters 0, and the plate Z) is provided with an outwardlyfiared inlet-opening b for the molten metal. The nozzle a of the pot is provided with one or more outlet opening or openings a, through which the metal passes into the mold in the well-known manner. The plate 6 is ,formed with recesses y, and between these recesses the opening I) is situated. Thus it will be evident that when the mold has been filled with molten metal and the plate is moved to break off the bur this bur will be broken off between the two full cast ledges formed at 2 11 and thus the rough broken edge will be located below the standard type height, as represented by the ledges l In Fig. 2 two openings 12 are provided, and a further recess is provided between the same, so as to form three elevated ledges on the slug.

In Fig. 3'the bur is broken ofi at thec0rner so that a somewhat narrower ledge of the proper height will extend all along the back of the slug.

From the above description it will be clear that the formation of the slide-plate according to the present invention obviates the necessity hitherto existing of smoothing off the back of the slug after the bur has been broken off. It further prevents the formation of spongybacks, which was hitherto due to the back stroke of the potplunger previous to moving the pot-nozzle back or away from the mold.

I claim as my invention 7 1. In a linotype-machine having a movable slide inserted between the mold and the potnozzle, the combination with said slide of means for removing the bur from the back of the slug when the slide is moved, at a point below the full height of the slug as represented by solid full cast ledges at the back of the slug substantially as described.

2. In a linotype-machine of the class specified, the combination of a movable slide haw ing projections at suitable points of the length former and for afterward brealiing'thespriie to of the type-line to be cast, said projections away from the linotype. extending partially into the mold and having In testimony whereof I have signed my metal-inlet openings within their length, snbname to this specification in the presence of 5 stantially as described. two subscribing witnesses.
